So I am working on this project idea that would allow a web user to enter a name and choose some options and from this the website will build a custom video. I will be using ffmpeg to merge images so that is not the problem but injecting the name into one of the video clips I am stuck with. Is there anyone that can give me some help? I haven't started coding anything yet and I am open how the individual video clips should be generated and with what software. Any advice?
